Abstract

Linear actuator mechanisms (100) for vehicle disconnect/connect systems having a stationary guide rod (122); a shift fork (118) the stationary guide rod extends therethough; a drive nut (110); a drive screw (120) extending through the drive nut; a first spring plate (114), a second spring plate (116), and a compression spring (112) positioned between a radially extending portion of the first spring plate and a radially extending portion of the second spring plate. A second radially extending portion of the first spring plate and a second radially extending portion of the second spring plate are in contact with the drive nut on axially opposite sides of the drive nut. The first and second spring plates are moveable axially along the stationary guide rod by the drive nut to compress the compression spring.
